no service, no response, since 20 July

further to my post on 11 July 2015 in which i complained about lack of signal and ongoing dropped signal at my office and home and on the roads of sandton, I have not had a satisfactory response or solution from MTN and its imps. Ive completed complaints forms, sent my GPS location, explained where i lose signal, received a form for what seems like a booster but without any forwarding information or cost or risks. To this mail i rep**** phone me. they didnt. they sent another mail. i rep**** PHONE ME and EXPLAIN what this is about, costs etc. they did not. someone else mails me. Shereen Motale escalaets to Lucky. they MAIL me i\have you completed the lease agreement."i say CALL ME to discuss"
